Fertilizer composition including animal manure and cement kiln dust

Abstract

A composition for use as fertilizer includes cement kiln dust and animal manure. The content of cement kiln dust and animal manure in the composition is selected as a function of either weight or volume. The content of cement kiln dust is greater than or equal to the content of animal manure. The fertilizer composition is formed by mixing the cement kiln dust and animal manure at ambient temperature and pressure.

What is claimed is: 
     
       1. A method comprising:
 mixing a volume of cement kiln dust with a volume of animal manure; 
 drying the mixture to form a fertilizer composition having pH in a range from 12 to 13, inclusive; and 
 distributing the fertilizer composition over agricultural soil. 
 
     
     
       2. The method of  claim 1 , wherein the volume of cement kiln dust and volume of animal manure are mixed at ambient temperature and ambient pressure. 
     
     
       3. The method of  claim 1 , wherein the volume of cement kiln dust is equal to or greater than the volume of animal manure. 
     
     
       4. The method of  claim 1 , wherein the animal manure is liquid cow manure. 
     
     
       5. The method of  claim 1 , wherein a ratio of the volume of the cement kiln dust to the volume of animal manure is in a range from 1:1 to 3:1, inclusive. 
     
     
       6. The method of  claim 1 , wherein the mixture consists of cement kiln dust and animal manure. 
     
     
       7. A method comprising:
 mixing cement kiln dust with animal manure to form a mixture, wherein a weight percent of the cement kiln dust in the mixture is greater than or equal to a weight percent of the animal manure in the mixture; 
 drying the mixture to form a fertilizer composition having pH in a range from 12 to 13, inclusive; and 
 distributing the fertilizer composition over agricultural soil. 
 
     
     
       8. The method of  claim 7 , wherein the weight percent of cement kiln dust is in a range from 50% and 70%, inclusive, and wherein a remainder of the composition is the animal manure. 
     
     
       9. The method of  claim 7 , wherein the animal manure is liquid cow manure.
